A Direct Measurement Of The Ratio Of The Reaction Cross Sections For Two-Photon And Three-Photon Positron Annihilation In Aluminum And Silver, Robert Maurice Heavenrich

Masters Theses

The probability of annihilation of a positron with its antiparticle, an electron, is spin dependent. Since both particles have spin component one -half, there are two possible relative orientations of their spins they can either be aligned (parallel) in the ³S, triplet, state with total spin component │S_z│= ½ n - ½ n = 1 n or they can be opposite (antiparallel) in the ¹S; singlet, state with│S_z│= ½ n - ½ n = 0. To conserve energy and angular momentum, annihilation from the triplet state must result in the creation of an odd …

Initial Feasible Solutions Of Three Dimensional Transportation Problems, Mamoru Aiga

Masters Theses

The purpose of this paper is to investigate methods to obtain initial feasible solutions of three dimensional transportation problems. Schell's procedure was tested on various randomly generated problems, and it was determined that this algorithm did not always yield an initial feasible solution. Thus a modified Schell procedure was developed.

Computer programs were written to compare the modified Schell procedure with Phase I of Simplex method. It was concluded, from cases tested, that the modified Schell procedure requires much less computing time and generally gives a feasible solution closer to the optimum solution.

Geology Of The East Fork Mine And Vicinity, Sevier County, Tennessee, John Charles Brower

Masters Theses

The East Fork mine consists of a series of open cuts in steeply dipping low-grade metasediments of the Late Precambrian (?) Ocoee Series. In general the metasedimentary units strike northeast and dip steeply to the southeast. However, interpretation of stratigraphy and structure is complicated by intensive local folding and faulting. Two large thrust faults occur in the southern part of the study area, and two or more thrust sheets comprise the bulk of Dixon Mountain in the eastern part of the study area. At the southern boundary of the study area, the Dunn Creek fault thrusts rocks of the Snowbird …

Implications Of Photogeologic Linears In The South Long Lake Area, Alpena And Presque Isle Counties, Michigan, Richard E. Kimmel

Masters Theses

There are numerous linear features in Alpena and Presque Isle Counties, Michigan, which are generally visible on aerial photographs. These photolinears trend in two general directions, northeast-southwest and northwest-southeast. These two sets are perpendicular to each other, and represent vector means of two fracture sets.

The development of the photolinears began in Early Devonian. Throughout its history, ground water flowed along underground channels connecting fracture intersections. This underground drainage network is responsible for many of the photolinears. Some of the photolinears can be attributed tb Early Devonian ground water activity and subsequent collapse of the Salina Salt basin, and some …

A Study Of A New Hydrometallurgical Treatment For New Lead Belt Chalcopyrite Concentrates, Larry Steven Livingston

Masters Theses

"A two-phase research project was conducted on chalcopyrite concentrates from the New Lead Belt of Missouri. Phase one includes an ore microscopy study of the Magmont and Viburnum chalcopyrite concentrates in respect to mineralogy, particle size and interlocking characteristics of ore minerals and their possible relationships to poor chalcopyrite-galena separation in the copper flotation circuits.

Results of the ore microscopy study of the Magmont and Viburnum mines chalcopyrite concentrates suggest that interlocking of chalcopyrite and galena are not the cause of poor chalcopyrite-galena separation in the copper flotation circuits.

The most common sulfides found in the Magmont and Viburnum chalcopyrite …

Monte Carlo Simulation Of Confidence Intervals For Reliability, Kathryn Palisch Berkbigler

Masters Theses

"A computer program which computes fiducial confidence intervals for reliability by Monte Carlo simulation has been written. The program has the capability of computing these intervals for general systems of series, parallel, and mixed series and parallel subsystems which have failure time distributions which are either exponential, Weibull, gamma, normal, or lognormal.

Comparison of the simulation technique with a Bayesian technique for computing confidence intervals in the case of a series of exponentially distributed components shows that the two methods agree quite well when a fiducial prior distribution for reliability is used in the Bayesian technique. A uniform prior distribution …

Model Correction For The Formation Of Amorphous Silicon By Ion Implantation, John Robert Dennis

Masters Theses

"ESR has been used to study the formation of an amorphous layer in silicon by ion implantation. The room temperature implants were done at 20 keV with low dose rates. The critical dose was determined as a function of ion mass for six different ion species. Our experimental heavy ion results agree with those found by other ESR investigators at higher energy, but are not the same for light ions. However, our light and heavy ion results agree with electron microscope measurements for low energy implants. An energy-independent model for the formation of amorphous silicon by ion implantation has …

Corals Of The St. Louis Limestone In The Area Of Calhoun County, Illinois And St. Louis County, Missouri, William Earl Collins

Masters Theses

"The St. Louis Limestone and its equivalent formations crop out from Alaska south to Sonora and from Arizona east to Virginia. The St. Louis, in most cases, is fossiliferous and contains numerous species of foraminifers, echinoderms, bryozoans, molluscans, brachipods, arthropods and coelenterates. Algal mounds and mats are common. The rugose coral fauna of the Middle Mississippian (Meramecian) St. Louis Limestone of southern Calhoun County, Illinois and northern St. Louis County, Missouri was studied to determine first what corals were present and second the validity of the names assigned to the previously described species. It was found that the binomen for …

The Design And Calibration Of A Vibrating Sample Magnetometer, Donald Dwight Hoffman

Masters Theses

"The design and calibration of a vibrating sample magnetometer is described. The sample motion was in the direction of the external magnetic field which was produced by a superconducting solenoid. The maximum external magnetic field was 70 kilogauss. Sample temperature could be varied from 77°K to 1000°K with a vacuum jacketed furnace. The maximum temperature was obtained with approximately 27 watts. The instrument was calibrated to 1% with a spherical nickel sample"--Abstract, page ii.

Mechanistic Studies Of Cobalt Super Nucleophiles, Audrey Yeh Ku

Masters Theses

A study was initiated on the hypothesis, by Ugi and co-workers, that cyclopropyl, cyclobutyl, and cyclopentyl electrophiles might undergo nucleophilic substitution reactions with retention of configuration.

A simple, high yield synthesis of both cis and trans-2-phenylcyclopropyl chlorides from styrene and chloroform is described. Reaction of each of these alkylating agents with the very nucleophilic cobaloxime super-nucleophile ultimately gave peroxy compounds which appear to arise from insertion of oxygen into the carbon-cobalt bond.

Neither trans-2-phenylcyclopentyl tosylate nor trans-2-phenylcyclohexyl tosylate would alkylate low valent cobaloximes under standard conditions.

A partial synthesis of the 2-phenylcyclobutyl tosylate is described along with suggestions for future …

A Study Of The Ability Of Surface Active Materials To Increase The Evaporation Rates Of Small, Freely Falling Water Drops, David Alan Sierawski

Masters Theses

"The evaporation rate at 30°C of water droplets partially covered by surface active materials (SAM) were determined. While two of the SAM were studied at a single dew point depression (ΔT_DP), seven others were examined over a range of ΔT_DP values. It was found, by comparison with pure water drops under identical conditions, that SAM increases the evaporation rate as compared to the rate of an uncontaminated drop. The lack of effect of the hydrophobic chain length and the possible effect of the hydrophilic group on this phenomenon are discussed. The explanation proposed is that at 30°C …
